[DmitryLitvintsev]

It looks like listing via webdav incurred 10 second delay ..... A listing of single entry directory takes > 10 seconds.

    webdav: wait for upload to complete
    
    Motivation:
    Due to a race condition between file upload and file's checksum
    availability a quick client might see no checksum after upload.
    
    Modification:
    Update webdav door to retry the request to the namespace if checksum is
    not present in files attributes.
    
    Result:
    
    Fixes: #7467
    Ticket: #10510
